The example then calls ExecuteNonQuery and closes the connection. The SqlCeConnection is opened and set as the Connection for the SqlCeCommand. The following example creates a SqlCeCommand and a SqlCeConnection.

System.Object System.MarshalByRefObject Example Use the following code to change the default behavior of SQL Server Compact 3.5 SP1 to work within ASP.NET.Ī('SQLServerCompactEditionUnderWebHosting', true) Inheritance Hierarchy SQL Server Compact 3.5 SP1 can be used with ASP.NET in application scenarios where ASP.NET is used to create SQL Server Compact 3.5 SP1 databases for synchronization scenarios. Other editions of SQL Server, including SQL Server Express, are optimized to serve as a database for Web sites. Therefore, these scenarios are not supported. Using SQL Server Compact 3.5 SP1 as a database for Web sites requires support for multiple users and concurrent data changes. SQL Server Compact 3.5 SP1 is optimized for use as an embedded database within applications. By default, connections from ASP.NET-connected applications are blocked in SQL Server Compact 3.5 SP1. SQL Server Compact 3.5 SP1 is not currently optimized to serve as a database for Web sites.

You can reopen the connection and continue. If a fatal SqlCeException is generated by the method executing a SqlCeCommand, the SqlCeConnection may be closed. This means that you can have multiple instances of SqlCeDataReader open on the same connection. SQL Server Compact 3.5 SP1 supports multiple simultaneous connections as well as multiple commands that share the same connection. You must explicitly close the connection by calling Close or Dispose. If the SqlCeConnection goes out of scope, it is not closed.

For a list of these values, see the SqlCeConnection constructor. When you create an instance of SqlCeConnection, all properties are set to their initial values. Public final class SqlCeConnection extends DbConnectionĪ SqlCeConnection object represents a unique connection to a data source.
